Septic systems process residential waste for properties not connected to a municipal sewer line. They operate differently from traditional waste disposal methods, so they can be confusing for people who aren’t familiar with them. If you’re considering purchasing a property with a septic tank, ask these questions before signing any papers. 

What to Know About Properties With Septic Systems

Where is the tank located?

Every property owner needs to know the exact location of the tank and leach field. Structures can’t be built over these components, and vehicles shouldn’t be parked or stored on them either.

The added weight can cause the tank to shift and crack, and it also compacts the soil in the leach field and decreases its efficiency. Also, knowing where the tank is located makes it easier to get the service it requires.

What material was used to construct the tank?

Understanding the type of tank on the property will prepare you for potential problems. The three main types are concrete, steel, and fiberglass.

Concrete tanks are incredibly durable, but they can be susceptible to cracking if built with low-quality mixtures. Steel tanks can last 20 to 25 years. They’re prone to rust, so ask when the tank was initially installed and have an inspection performed to detect water damage.

Fiberglass tanks are mostly immune to rusting or cracking, but the plug at the bottom can become dislodged. If there are low levels of effluent in the container, make sure the plug can be reinstalled.

How often has it been serviced?

Septic tanks require pumping once every three to five years. If the tank on the property hasn’t received regular maintenance, solid waste can drain into the leach field and diminish its ability to accept additional effluent. This leads to unprocessed waste backing up into the home’s plumbing, so always ask to see the system’s service and pumping history.

Knowing the previous owner’s pumping schedule can also help you determine yours. If their four-person family needed a pumping appointment every four years, schedule more frequent service for your five-person household.

Is it a shared system?

Sometimes property owners will connect multiple homes to the same system, which can lead to problems in the future. The tank will require pumping services more often because it’s processing twice as much waste. You also have to ensure that everyone in the other residence understands what items can’t go into the tank, such as cotton products, oil or grease, and flushable wipes.
